Cerium Hexaboride Industrial Grade 99.9%

Cerium hexaboride is dark gray powder, which is a rare earth boride. It has relatively low work function that is about 2.5 eV, so decide it is cathode material of extremely high electron emissivity. It is also a refractory ceramic material. Cerium boride is stable in vacuum. CeB6 is dense Kondo-like behaviour. It has better resistance to carbon pollution and longer life than lanthanum boride cathode. Its working temperature is 1450℃ usually.  CeB6 like LaB6 will slowly evaporate at working period. Cerium boride is insoluble in water.

Applications

Cerium hexaboride mainly uses for a coating of hot cathodes, or cerium boride crystal makes up hot cathodes directly. CeB6 and LaB6are usually used for some coating of high current hot cathode with heavy current. CeB6 cathode has lower evaporation rate than lanthanum boride below 1700K, but they get to same and even higher evaporation rate at 1850K. It has 50% higher life than LaB6 due that it has better resistance to carbon pollution. The brightness of boride cathode  is 10 times than tungsten cathode and at same time its life is 10-15 times higher than tungsten cathode. Their common uses are electron microscope, microwave tube, electron beam lithography, electron beam welding, X-ray tube and free electron laser.

Cetrimonium Bromide

Cetrimonium bromide is one of the components of the topical antiseptic cetrimide. The cetrimonium cation is an effective antiseptic agent against bacteria and fungi. It is a cationic surfactant. Its uses include providing a buffer solution for the extraction of DNA. It has been widely used in synthesis of gold nanoparticles. It is also widely used in hair conditioning products.

Properties Suppliers
Cetylpyridinium Chloride, Monohydrate, USP

Cetylpyridinium chloride (CPC) is a cationic quaternary ammonium compound in some types of mouthwashes, toothpastes, lozenges, throat sprays, breath sprays, and nasal sprays. It is an antiseptic that kills bacteria and other microorganisms. It has been shown to be effective in preventing dental plaque and reducing gingivitis. It has also been used as an ingredient in certain pesticides. However, this ingredient has also been alleged (according to WebMD, eMedicine,) to cause brown stains between the teeth similar to chlorhexidine rinse. Flossing one's teeth regularly and with good technique will prevent this type of extrinsic staining.
